摘要
编织卷积码(WovenConvolutionalCodes)是近年来所出现的一种新型高效纠错码,其中交织器的设计对分散突发错误、改善其纠错性能起着决定性的作用。传统的编织卷积码采用了行进列出的简单的交织方式,本文针对编织卷积码的结构特性设计了两种不同的交织器并通过系统仿真比较了它们的性能,仿真结果显示行式交织器极大地改善了系统性能,是目前为止最优的编织卷积码的交织器。
Woven Convolutional Codes (WCCs) introduced in this years is a new efficient error-corrective codes, good interleavers can scatter burst errors and improve its error-corrective performance. Conventional WCCs use interleaver which writes the information sequence in row and reads code sequence in column. In this paper, two additional interleavers are designed, simulation result shows that row-wise interleaver improve performance greatly which is the best interlaver for WCCs.
